IntroductionCompany Introduction

Linear Actuators


IntroductionProduct Introduction

Actuators offer advantages over mechanical and hydraulic systems in many applications. They are self-contained, rugged, and durable, making them ideal anywhere you want to lift, lower, push, pull, rotate or position a load.

Compact designWith their compact size, actuators can be located in confined areas. An actuator with a 100 mm stroke length can produce 9000 N of force from a 290 mm package. Electrak 1 and 050 series actuators fit small areas with package lengths as short as 115 mm.

Rugged and reliableAll Thomson actuators incorporate strong, high quality components to assure trouble-free service. Rugged spur, worm or helical gearing, aircraft quality lubricants and high performance motors provide the maximum life and value. The actuators are gasketed and sealed throughout for protection in wet, dirty and oily environments and are ideal for use on outdoor equipment. The rod style actuators have stainless steel or aluminum extension tubes to resist corrosion.

Maintenance-freeAll adjustments and lubrication are made at the factory and no maintenance is required or recommended. Consistent,

repeatable performance is provided for the entire lifetime of the actuator.

BidirectionalThomson actuators can push and pull loads ranging from one to 900 kg, and can extend up to 900 mm. With the Thomson series of actuator controls, you can create an actuator control system to meet your particular motion control requirements.

Safe operationMotors used on Electrak actuators utilize thermal switches in their windings or Electronic Load Monitoring to shut the actuator off in case of overheating. A standard overload clutch or Electronic Load Monitoring will stop the motion if the load is too great or at the end of a stroke. All linear actuators will hold their loads with power removed.

Versatile Stroke lengths of 25 to 1500 mms are available and speeds are as high as 110 mm per second. Actuators are easy to apply, quick to install and usually only requiring two wires for operation. A wide variety of options and controls makes it easy to find the perfect actuator for your application. And if you have special needs, cost effective custom solutions are our speciality.

Thomson actuators are easy to mount and operate, require no maintenance, don’t leak hydraulic fluid, are easy to incorporate into an automated process and once installed they will work reliably under the toughest conditions year after year.

Electrification is converting manual, hydraulic and pneumatic operations to electromechanical motion. Substantially improved machine performance and cost advantages can be gained through electrification.

Reduce costs• Electric actuation components cost less than comparable hydraulic and pneumatic systems. • One electric linear actuator is faster and easier to install than the multiple hydraulic and pneumatic components required to achieve the same function. • Electric actuators feature quick and predictable system tuning when compared to the headaches of configuring hydraulic systems and their components which contend with power variation, temperature variation, and non- linear performance profiles.• Compare zero maintenance electric actuators against the fluid replacement, leak repairs and other routine maintenance needed to support hydraulic systems.• Eliminate the environmental problems and costs associated with hydraulic fluid leaks and fluid disposal.

Boost productivity and efficiency• Improve control over critical machine operations with: - Multiple digital and analog feedback options - Fixed and programmable limit switches for “teach and repeat” positions - Low voltage switching options that can interface directly with programmable PC/PLC controllers - Pulse width modulation for variable speed control• Superior accuracy and repeatability• Link and automate simultaneous processes • Reduce down time with: - Zero maintenance - Longer component life - Redundancy through manual override• Improve safety and reduce costs by removing people from danger with convenient remote control

Great opportunities for electric conversion Making jobs easier • Raising and lowering a deck on a mower, paver or floor scrubber.• Shifting manual transmission.• Lifting wheelchairs into a vehicle.• Opening and closing doors on buses or vans.

Automating a process • Moving twine across a round bale of hay for consistent wrap.• Varying the chute opening on a salt/sand spreader based on speed for consistent application.• Lift and lower pantographs on electrical trains and trams.

Providing remote control• Throttle control from the rear of garbage trucks.• Positioning the discharge spout on a large chipper, snowblower or combine.• Opening a chute on a salt/sand spreader.• Positioning of solar energy panels and wind power plant turbines.• Opening/closing the engine hatch on boats.• Positioning boat, handicap vehicle seats.• Belt tensioning.

Removing people from danger • Sliding a cover over the stairs in a recreational vehicle.• Throttle control for a tree stump grinder to keep the operator away from moving parts or flying debris.• Medical waste/refuse compacting.

Replacing hydraulics or pneumatics• Power steering.• Dump beds on ATVs.• Positioning mower decks on golf course equipment.

IntroductionThe Benefits of Electrification

Linear Actuators


Replacing hydraulic or pneumatic cylinders with electrical linear actuators means a simpler and smaller installation, easier control, lower energy costs, higher accuracy, less maintenance, less noise and a cleaner, healthier environment.

IntroductionThe Benefits of Electrification

Single acting, uni-directional hydraulic cylinder system1. Hydraulic cylinder2. Electric pump motor3. Hydraulic pump4. Hydraulic oil resevoir5. Check valve6. Operator push button box7. Relay cabinet8. Unloading valve

This single acting, uni-directional hydraulic cylinder system is one of the simplest hydraulic solutions. This system only allows consistent performance in one direction. In order to get consistent performance in both directions a bi-directional system would be required which is even more complex and costly.

You can design, purchase and install all these components or you can select and install an actuator and control.

Plug and play type of connections, simple installation and no need for any set up or adjustments ensures accurate, clean and trouble free operation within the hour.

This simple electrical actuator system will ensure consistent operation in both directions. It will also give you added features such as electronic load monitoring, end of stroke limit switches, mid stroke protection and manual override operation in case of power failure. Optional features such as analog or digital position feedback, adjustable end of stroke limit switches, end of stroke indication outputs and signal following capability are also available. Another advantage is that a system like this is easy to integrate with other control systems normally found in industrial systems or vehicles such as PLC’s, micro-controllers, computers or simple relay based systems.

IntroductionActuator Applications

Linear Actuators


Thomson actuators have been divided into good, better and best groups to help you select the appropiate actuator for your application. By using the simple selection procedure described below and the Performance Overview on the next few pages, the process will be even easier.

GoodThese actuators are the lowest cost solution, provide capable, reliable performance and have some flexibility of options and configurations. If you just need a basic actuator, this is the best choice.

BetterThese actuators have more flexibility in options, configurations and modifications. They have passed the test of time in the toughest agriculture and construction applications. Choose from this group if you need a rugged, heavy duty actuator customized to your application.

BestThese robust and strong actuators are the market leaders with state of the art technology and flexibility. They are smaller, lighter and have a shorter retracted length than other actuators on the market. If you need electronic load monitoring, programmable limit switches, digital feedback or signal following, this is the group for you.

Selection procedureStep 1 - Determine VoltageDC actuators can be operated by battery, a rectifier or an actuator control with 230 Vac input. AC actuators are either 230 or 400 Vac.

Step 2 - Determine Load/SpeedSelect the actuator which has the load and speed rating that suits your application.

Step 3 - Select Stroke LengthChoose the desired stroke length from either the Performance Overview pages or the individual product pages.

Step 4 - Verify Design ConsiderationsDo you need a very short retracted length, adjustable, fixed or programmable limit switches, electronic load monitoring, digital or analog feedback, low voltage power switching, manual override, signal following, clevis mounting, tube mounting or trunnion mounting? If you need an actuator to take side loads or cantilever loads, select from the TC16, DMD, DMA or LM80 actuators.

Step 5 - Select ControlThe controls in the catalog are designed for use with Electrak actuators and range from a simple switch to a control with membrane switches and feedback display or with a hand pendant.

Acme ScrewAcme screws are self locking and will not backdrive. They also withstand vibration and shock better than ball or worm screws and are used for applications with these characteristics. Also see “lead screw”.

Actuator HousingThe actuator housing provides environmental protection for the internal components and may also be a structural member of the actuator.

AdaptersThe front and rear adapters are the connection points for mounting most Danaher Motion actuators. The front adapter is usually a cross hole but optionally may be a tapped hole, threaded rod, or universal rod end. The rear adapter may be cast into the actuator housing or held in place with a nut.

Adjustable End of Stroke Limit SwitchesThe adjustable end of stroke limit switches may be moved to positions inside the full stroke of the actuator and will shut off the actuator when it reaches the limit switch. Also see “end of stroke limit switches”.

Anti Coast Brake/Electrical BrakeDepending on the load, AC ball screw actuators may coast to a stop when power is removed. This overrun is eliminated by an anti coast brake or an electrical brake. The anti coast brake (pawl type) will allow up to one revolution of the motor after power is removed. They are used on the Electrak 5 and PPA-AC with anti coast brake. An electrical brake (electrically released) operates much faster after power is removed and allow less coast than the pawl type. Electrak 205 and the PPA-AC with electrical brake use this type of brake. Also see “brake”.

Anti Rotation MechanismA feature available on some actuators that resolves the restraining torque within the actuator. The extension tube will not rotate on actuators with this feature.

Auto Reset Thermal SwitchAn auto reset thermal will switch off the motor if it becomes to warm which means that the motor has exceeded its maximum allowed duty cycle. When the motor has cooled of the switch will close again automatically and the motor will start to run if power still is being applied to it. Also see “duty cycle”. Ball ScrewBall screws are highly efficient and are used for high loads and speeds. Also see “lead screw”.

BrakeActuators using a acme or worm screw are inherently self-locking while ball screw driven actuators are not. To prevent ball screw actuators from backdriving they incorporate an anti backdriving brake (holding brake). Ball screw actuators with an AC motor can also be equipped with an anti coast brake. Also see “anti coast brake/electrical brake” and “holding brake”.

CapacitorThe ac actuators use permanent split capacitor motors and require the use of a start/run capacitor in the control circuit to operate. The controls for the ac actuators have the capacitor included in the control. For customer supplied controls, a separate capacitor is required and the part number is included on the actuator product page.

CertificatesCE certification and UL listing are the two main third party approvals available for actuators. Most of the AC actuators are UL listed as standard and UL has no standard for DC actuators under 48 Vdc. All actuators sold in the EU are CE certified while some actuators sold outside of the EU may not be. If you order your actuator outside of the EU and need a CE certification, contact the factory to verify availability and be sure to include the request on your order.

ControlsControls can be external to the actuator and provide the actuator with the correct voltage, have either membrane or pendant operators and some have position indicators. The Pro series also has internal controls that continuously monitor the operation of the actuator.

Cover TubeThe cover tube provides protection for the lead screw and provides protection and support for the extension tube. For the Electrak 100 and PPA and as an option on the Electrak 205 actuators, the cover tube also provides the rear mounting connection.

CustomizationEven the most versatile actuator may not always suit all applications. But whatever your need is, our engineers are ready to help you to customize the actuators according to your requirements. We build more exclusive actuators than anyone else and have decades of experience of producing actuators to meet special needs.

Example: 15 seconds on, 45 seconds off

15 s

(15 s + 45 s) = 25% duty cycle

The duty cycle is a function of the maximum rated load and the ambient temperature. Ambient temperatures above the stated will affect the duty cycle negatively while lower temperatures and/or lower load will affect it positively. Review the following duty cycle versus load charts when higher duty cycles are needed for Electrak 1, Electrak 10 or DMD actuators. Electrak 1, Electrak 1SP

Dynamic Load The dynamic load rating is how much load the actuator will move when power is applied. Also see “load rating”.

Dynamic BrakingDynamic braking is a feature on the Pro series which short circuits the motor windings at power off resulting in a shorter

coasting distance before the actuator comes to a complete stop. Dynamic braking can be accomplished on other dc actuators by wiring the control to short the motor leads when power is removed.

Electronic Limit Switches (ELS)ELS stands for Electronic Limit Switches and it is a current sensing function used in some actuator control models. The ELS senses the current and if the current exceeds a pre-set level the control cuts the power to the motor. This function can be used to detect and stop at the ends of the actuator stroke or to stop the actuator if it runs into an obstacle.

Electronic Load Monitoring (ELM)A built-in microprocessor inside the Pro series actuators continuously monitors the performance of the actuator. The microprocessor will stop the movement at the end of stroke, in case of mid stroke stall, at overload conditions or if the duty cycle is too high. It also eliminates the need of a clutch and provides dynamic braking.

Encoder FeedbackEncoders provide a digital output signal that can be used to determine the position of the extension tube. An encoder equipped actuator must return to a “home” position if power is removed and restored in order to reset its starting point. Also see “potentiometer feedback”.

End of Stroke Limit SwitchesEnd of stroke limit switches are switches that are incorporated in some actuator models, either as standard or as an option, that will shut off power when the end of stroke is achieved. Also see “fixed end of stroke limit switches” and “adjustable end of stroke limit switches”.

End Play (Backlash)The stack up of tolerances within the lead screw assembly and gearing allowing some linear movement of the extension tube without rotating the motor. Typical end play or backlash varies by model. The range is 0,3 to 2,0 mm.

Extension TubeThe extension tube slides in and out of the actuator and is connected via the front adaptor to the load being moved or positioned.

Fixed End of Stroke Limit SwitchesThe fixed end of stroke limit switches allow the full stroke of the actuator to be used and will shut off power when the end of stroke is achieved. Also see “end of stroke limit switches”.

Electrak 5, DMA - Ball Screw Models

GlossaryEx – LifeHolding BrakeThe Electrak 1, 2, 050, 150 and some Pro series incorporate an acme screw which is inherently self-locking while Electrak 5, 10, 100, 205 and the high load Pro series actuators have a ball screw drive incorporating an anti backdriving brake (holding brake) that engages when the actuator has come to a complete stop. Also see “brake”.

Input VoltageThe nominal voltage required to operate the actuator. All actuators will accept at least a ± 10 % variation of the nominal voltage but a change in the voltage will result in a change of the speed of dc actuators. Controls are available that accept 115 or 230 Vac input and provide 24 Vdc output to operate 24 Vdc actuators.

Installation InstructionsEach actuator has an installation manual to answer typical questions about mounting and wiring the actuators.

Lead ScrewActuators use four different types of lead screws depending on the configuration and load requirements of the actuator. Ball screws are highly efficient and are used for high loads and speeds. Acme, worm and trapezoidal screws are self locking and will not backdrive. Acme and trapezoidal screws withstand vibration and shock better than the other and are used for applications with these characteristics.

Lifetime ExpectancyLife is a function of load, stroke length and how often the overload clutch is operated. The following life versus load charts will provide a life estimate for your particular application. Contact customer service for more information or for information on other actuator models.

The above chart is only valid for ball screw models with rated load up to 4500 N and stroke lengths up to 12 inch. Contact customer service if you need life estimates for acme screw models or for higher loads or longer stroke lengths.

Lifting ColumnsLifting columns provide a stable base for adjusting the height of tables or platforms. The column provides both the lifting force and the ability to resolve high moment forces from off axis loads.

Linear ActuatorsActuators providing a linear thrust via an extension tube to lift, lower, push, pull or position a load.

Load RatingThe load rating is the minimum amount of force the actuator will provide during its lifetime. The load rating of all rod style actuators is the same for both compression and tension loads. Also see “dynamic load”, “static load” and “tension and compression load”.

Manual Override (Hand Wind)Allows manual operation of the actuator in both directions in case of a power failure. The actuator accepts a standard hexagon key to rotate the motor in either direction. Optional on some models and standard on the Pro series.

Maximum On TimeThe maximum amount of time an actuator may operate without stopping to “cool off”. For high load and long stroke actuators this may be one extend and retract cycle. The actuator should not exceed 25% duty cycle at full rated load. If no maximum on time is stated then the maximum on time are equal to one full cycle at the maximum dynamic load for the actuator in question.

MountingElectrak actuators are quickly and easily mounted by slipping pins through the holes on each end of the unit and into brackets on the machine frame and the load. Electrak 100 units must be mounted by the cover tube and a swivel rod end. PPA actuators are mounted by the rear trunnions on the cover tube and the clevis on the extension tube. The Electrak 205 can be mounted by either the rear clevis or by a tube mount. 12,7 mm diameter solid pins (6,35 mm solid pins for Electrak 1 and 050) provide maximum holding strength and a retaining or cotter pin on each end will prevent the solid pin from falling out of its mounting bracket. Roll or spring type mounting pins should be avoided. The mounting pins must be parallel to each other as shown below (Fig. a). Pins which are not parallel may cause the actuator to bind. The load should act along the axis of the actuator since off center loads may cause binding (Fig. b).

Fig. a Fig. b

Non-driven ActuatorsActuators supplied without a motor and driven manually or by a customer supplied motor.

Operating and Storage TemperatureThe operating temperature is the range in which the actuator may be safely operated. For the high end of the range, the duty cycle will be lower than 25 %. All actuators can be stored or transported at the same temperature as the operating temperature. Contact customer support if the operating temperature will be exceeded during storage or transportation.

Output VoltageOutput voltage is the voltage from the control to run the actuator. The controls for dc actuators have 24 Vdc output. The controls for ac actuators have either 115 or 230 Vac output.

Overload ClutchElectrak 050, 2, 5, 10, 100, 205 and PPA series linear actuators are protected by a load limiting mechanical clutch which prevents the motor from stalling at either end of the actuator stroke. It will also slip when the factory-set load limit is exceeded. The clutch is a ball detent design, assuring a consistent slip point and long life.

be speed controlled by PWM within certain limits without any adjustments except for the Pro series that due to the internal electronics must have a steady power supply.

Restraining TorqueThe torque which is developed between the clevis on the extension tube and rear mount(clevis or trunnion) when the unit extends or retracts and ratchets the clutch (Fig. c).

Fig. c

Rodless ActuatorsRodless actuators provide support for the load as well as thrust. The load is supported and moved by a carriage on the actuator rather than pushed or pulled by an extension rod. Rodless actuators are ideal for applications requiring long strokes (up to 1500 mm), high speeds (up to 110 mm/s), movement of the load within the shortest envelope possible or the load supported by the actuator.

RoHS ComplianceAll actuators, controls and accessories sold in the EU are RoHS compliant unless otherwise stated, while products sold outside of the EU may not be. If you order an actuator outside of the EU and need it to be RoHS compliant, contact the factory to verify availability and be sure to include the request on your order.

Rotary ActuatorsActuators providing a rotary output to position a load, turn a winch, or rotate a gear or sprocket.

Service and MaintenanceActuators are generally maintenance free. The Electrak 2, 5, 10, 100, 205 and Pro series have repair kits available from your local distributor or OEM.

Signal Follower Input / ControlAn optional control contained inside the Pro series actuators that will cause the extension tube position to follow a customer supplied potentiometer signal. Also known as a position follower control.

Sizing and SelectionThe Danahermotion.com web site includes a product advisor that can be used to walk through the decision process for picking the best actuator and to get the ordering data for your choice. Go

Potentiometer FeedbackPotentiometers provide an analog output signal that can be used to determine the position of the extension tube. A potentiometer will “remember” its position if power is removed and restored. All potentiometers are set to a minimum value on full retract except for the EU versions of Electrak 5 and Electrak 10 where the minimum value are set on full extend. Also see “encoder feedback.

Programmable Limit SwitchesAn optional control contained inside the Pro series to which an external programming box or customer supplied switches can be connected to set and reset the end of stroke limits as often as needed. The programming box has a “jog to position” switch and a “set limit” switch.

Protection ClassThe protection class refers to the environmental rating of the enclosure. The first digit applies to airborne contaminants and the second digit to water/moisture. IP33: protected against the penetration of solid objects with a diameter greater than 12 mm and against direct sprays of water up to 60 degrees from vertical.IP44: protected against the penetration of solid objects with a diameter greater than 1 mm and against water sprayed from any direction.IP45: protected against the penetration of solid objects with a diameter greater than 1 mm and low pressure water jets from any direction.IP51: protected from dust and vertical dripping water/ condensation.IP52: protected from dust and dripping water/condensation falling at an angle up to 15 degrees from vertical.IP56: protected from dust and high pressure water jets from any direction.IP65: dust tight and protected against low pressure water jets from any direction.IP66: dust tight and protected against high pressure water jets from any direction.IP67: dust tight and protected against the effect of immersion in water between 150 mm (5.9 inch) and 1 meter (39.4 inch).

Pulse Width Modulation (PWM)Pulse width modulation control works by switching the power supplied to the motor on and off very rapidly. The DC voltage is converted to a square-wave signal, alternating between fully on and zero, giving the motor a series of power “kicks”. If the switching frequency is high enough, the motor runs at a steady speed due to its fly-wheel momentum. By adjusting the duty cycle of the signal (modulating the width of the pulse, hence the ‘PWM’), the time fraction it is “on”, the average power can be varied, and hence the motor speed. All DC actuators can

SpeedDC actuators have a direct load/speed relationship. As the load increases, the speed of the dc actuators decreases. There are curves on each product page to show the speed from no load to full rated load. AC actuators have very little speed fluctuations based on load but there are load/speed curves on all the ac actuator product pages.

Spline Safety FunctionAn optional safety function on the rodless actuator (LM80) that will stop downward motion in case the carriage (the moving member) collides with an obstacle. The motor will keep running but the carriage will stand still and not pull down on the obstacle. When reversing the motor rotation the carriage will automatically start to move upwards again.

Static LoadThe static load rating is how much load the actuator will hold with power off. The static load rating is normally twice the dynamic load rating. Also see “load rating”. If nothing else is stated the static load rating is for the actuator extension tube being fully retracted. The static load rating will decrease as the tube extends.

Synchronous OperationMotor speed cannot be controlled with enough precision to ensure that the actuators will remain synchronized and a binding effect could take place. Non-driven actuators may be mechanically linked and thereby synchronized. Actuators equipped with an encoder can also be synchronized using controls designed for synchronous operation.

Tension and Compression LoadA tension load tries to stretch the actuator and a compression load tries to compress the actuator (Fig. d). Most actuators can manage the same tension and compression load. Also see “load rating”.

Trapezoidal ScrewScrew type with similar characteristics as an acme screw. This type of screw is used in TC16 and LM80. Also see “acme screw” and “lead screw”.

Vent TubeThe Electrak 050 and 150 have a breather tube in the wiring harness to allow the actuator to operate without creating a vacuum and drawing water through the seals on the cover tube.

Voltage DropLong leads/cables between the power source and the actuator will result in a voltage drop for DC units. This voltage drop can be avoided by sizing the leads in accordance with the following leadcross section selection table. The table is based on an ambient temperature of 30 °C or less. A higher ambient temperature may result in the need for a greater lead cross section.
